Abstract(J)走行中のタイヤは路面等からの励振力を受け,複雑な振動挙動を示す.しかし,高速な回転体であるので,ケーブルを有する接触式センサでは振動計測が難しい.そこで本研究では,圧縮センシングとデジタル画像相関法を用いて,突起乗り越し時におけるタイヤの詳細な振動形状と周波数スペクトルを計測する手法を開発した.

Translation

Abstract(E)Tyres in motion receive excitation forces from the road surface and exhibit complex vibration behaviour. However, as they are high-speed rotating bodies, it is difficult to measure their vibration using contact sensors with cables. This research therefore developed a method using compressed sensing and digital image correlation to measure the detailed vibration modes and frequency spectra of tyres when they are overriding a tyre-mounted protrusion.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
